ulcerative colitis is a chronic disease that specifically affects the mucosa of the rectum and colon. although the etiology of this recurring inflammatory disorder remains essentially unknown, there have been significant advances in identifying the likely genetic and environmental factors that contribute to its pathogenesis. the clinical course of the disease typically manifests with remissions...

Rapid environmental degradation in China makes understanding how perceived exposure to environmental harm influences environmental attitudes and participation in pro-environmental behaviors among the Chinese people crucial. We used a nation-wide survey dataset in urban China to test two hypotheses: experiencing environmental harm directly affects environmental behavior; environmental attitudes ...

The effect of spatial heterogeneity on species coexistence relies on the degree of niche heterogeneity in the habitat and the ability of species to exploit the available niche opportunities. We studied species coexistence in a perennial grassland, and tested whether small-scale disturbances create environmental heterogeneity that affects coexistence and whether the functional diversity of speci...

Extraction and transportation of mineral resources today presents an increasing social problem, leading to environmental damage and the violation of human rights. In addition to economic and social controversies as well as political problems (such as corruption amongst state and local authorities), it caused population displacement on a large scale. The social costs of oil production illustrate...

Environmental epigenetics has an important role in regulating phenotype formation or disease etiology. The ability of environmental factors and exposures early in life to alter somatic cell epigenomes and subsequent development is a critical factor in how environment affects biology. Environmental epigenetics provides a molecular mechanism to explain long term effects of environment on the deve...
